CHARLES GORTON, OE PHILADELPHIA, PENNSYLVANIA.

, STEAM-GENERATOR.

SPECIFICATION forming part of Letters Patent No. 280,606, dated July 3, 1883. Application filed April 21, 1883. (No model.)

To aZZ whom it may concern Be it' known that I, CHARLES GoRroN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Steam- Generators; and I do hereby declarev that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to the class known as upright steam-generators, and has for its object simplicity of construction, economy in fuel, to be easily manipulated, and an enlarged heating-surface, as well as cheapness in. first cost and repairs.

To this end my invention consists in constructing the boiler with a central fuel-magazine extending vertically through it and opening through the crown-sheet, and also through the top tube-sheet; and also connecting the crown-sheet and said tube-sheet by a series of vertical flame-tubes arranged around the magazine; and also connecting said tube-sheet with an annulus arranged on a plane below the crown sheet, and extending around and outwardly from the water-leg of the fire-box for the reception of another series of downwardlyextending flame-tubes, also arranged verti cally, and with an encircling jacket, all of which will more fully hereinafterappear.

Referring to the accompanying drawings, Figure 1 shows a central vertical section of my improved boiler. Fig. 2 shows a horizontal section taken on the line 00 x of Fig. 1.. Fig. 3 is a detached view in perspective, showing the contour of the crown-sheet B and annulus tubesheet E. Fig. 4 is aview of the cast-iron top of the casing. and Fig. 5 aview of the annular plate which holds the casing at its lower end.

The same letters denote like parts in all the figures.

A is the fire-box, B the crown-sheet, and

O the magazine. D is the top horizontal tubesheet, andE the annulus, which extends outwardly and around the fire-box at a point be low the crown-sheet, where it is secured to the water-leg. This annulus is of peculiar con struction, it being provided with two annular flanges, thus '1, somewhat Z-shaped, and marked a b, (see Fig. 3,) the flange b adapting it to be secured to the water-leg, and the flange a to the outer water-shell of the boiler.

d (I represent a series of flametubes which surround the magazine 0, arranged to break joints, and are connected to the crown-sheet B at their lower ends and to tube-sheet ,D at their upper ends. The series of tubes 6 0 connect the outer portion of the tube-sheet D with the circular plate or annulus E, and are for the purpose of conveying the smoke and flame downward to the lower smoke-chamber, F. These clusters or series of tubes are encircled on the outside with a cylindrical water jacket or casing, G, of metal of any desired strength or thickness, and which forms the outer wall of the boiler, and the inner water-wall is formed by the fuel-magazine, so that it will be seen that the water-space of the boiler is formed only of two cylindrical shells, and which are very readily attached to upper and lower tube-sheets, which form the upper and lower walls of the boiler.

The water-legs which form the fire-box extend below the annulus E, in which are located the grates.

The crown-sheet B and tube-sheet D, which carry the tubes, also carry the magazine.

011 the outside of the boiler I locate a light metal casing, H, the lower end of which is se cured and rests in a socketed cast-iron flange, which is secured to the water-legs of the boiler below the tube-annulus by means of the rightangled flange cast thereon. This casing H is much larger in all directions than the boiler, and forms on all sides of the boiler a heatingspace and smoke-chamber.

Extending entirely over the top of the boiler is locatedan imperforate cast-metal cover, I, except the opening for the magazine and steamsupply pipe. This cover is attached to and rests upon the outer sheet-iron casing some dismaterial, and a downwardly-soeketed projection, for the reception of the outer casing, said casing being held in position by the socketed flange east 011 the annular plate, which is secured to the water-legs at bottom, and at the top by the soeketed flange formed on the castiron cover.

The uptake may be located on any side most convenient to the chimney. The iced-water pipe may also be located at the most accessible position.

The usual safety appliances, furnace-doors, and other attachments are not shown, as they form no part of this invention.

The operation may be stated as follows: Fire being lighted in the furnace and the magazine full of fuel, the iiame and gases pass up through tubes (1 (1 into the smoke-box J, then down tubes 0 0 into the smoke-box F, and then up the annular space K, formed between the casing and water-wall of the boiler, as shown by the arrows. It is evident that this boiler is equally adapted to generating steam for house-heating as well as for supplying motive power to steamengines, and, being on the base-burning principle, the feeding of the boiler requires but little personal attention.

I am aware that the returirflue principle, as well as jaeketing boilers, is not new, and I am also aware that boilers provided with magazines have been made, and therefore do not claim such construct-ions; but I am not aware that a boiler constructed as mine is was ever before known.

Having thus described my invention, its constrnction and operation, what I elaim as new, and desire to secure by Letters Patent, is

l. The combination, in a steam-generator, of the fire-box, the iiiel-iiiagaziiie, the uptaketubes (1 d, the diving-tubes c (2, annulus E, the smoke-ehambers F J, and the annular chamber K, the outer casing being secured in the grooves in the top and bottom heads, all eonstrueted and arranged as set forth.

2. A steam-generator having magazine and fire-box, and having the up and down flame and smoke tubes, arranged as described, i 11 combination with the outer easing, and with its lower annular plate having an annular 500(- eted projeetion,and its top plate provided with a downwardly-s0cketed extension, and also an upwardlvproi eotin g annular flange for holding noneondueting material, said annular plate, easin g, andtop forming flame and smoke eham bers and passages, in the manner described, and for the purpose set forth.

Intestimony that I claim the foregoing as my own invention I afiix my signature in presenre of two witnesses.

CHARLES GORTON.
